CAMRT Radiography Practice Exam

The peripheral inserted central catheter (PICC line) is a medical device specifically designed for administering long-term nutrition, chemotherapy, and other intravenous therapies. It is inserted into a peripheral vein and threaded into a central vein, allowing for easy access to the bloodstream without the need for repeated needle insertions.

The design of a PICC line facilitates the delivery of fluids, medications, and nutrition over an extended period, often weeks or months, making it ideal for patients requiring ongoing treatment. The use of a PICC line minimizes discomfort and lowers the risk of complications associated with frequent venipuncture, providing a reliable method for managing complex medical needs.

In contrast, the nasogastric tube is primarily used for short-term feeding or stomach decompression, while a chest tube is designed to remove air or fluid from the pleural space and is not intended for nutrient delivery. A pacemaker is an electronic device used to regulate the heart's rhythm, unrelated to nutritional or chemotherapeutic needs. Hence, the PICC line stands out as the appropriate choice for long-term administration of essential medical treatments.
